Javascript – .Remove() function not working for MongoDb

This is constantly giving me error that Contact.remove() is not a function. I want to delete a particular contact by passing an id.

const DeleteContact = asyncHandler(async (req, res) => {

    const contact = await Contact.findById(req.params.id);
    if (!contact) {
       res.status(404)
       throw new Error("Contact not found");
    }
  
 
    await Contact.remove();
    res.status(200).json(contact);
});

    I would do something like this:

    const DeleteContact = asyncHandler(async (req, res) => {
  const contact = await Contact.findOneAndDelete({ _id: req.params.id });
  if (!contact) {
    res.status(404);
    throw new Error("Contact not found");
  }

  res.status(200).json(contact);
});

    Your error is probably because of using delete instead of deleteOne, i think they recently had a change on their function names

    You should use Model.findByIdAndDelete() if you know the _id of the document to would like to delete like so:

    const DeleteContact = asyncHandler(async (req, res) => {
   try{
      const contact = await Contact.findByIdAndDelete(req.params.id);
      if (!contact) {
         return res.status(400).json({
            message: 'Unable to delete. Contact not found.'
         })
      }
      res.status(200).json(contact);
   }catch(err){
      console.log(err);
      return res.status(500).json({
         message: 'Error on server.'
      })
   }
});

    Note: the try/catch may be unnecessary if your asyncHandler is well written but I did not want to assume.
